Skitter is a jQuery plugin that enables us to convert unordered lists into slideshows with attractive animations.
The slideshow can display the list of slides as numbers or thumbnails and items can be browsed with the help of prev-next buttons as well.
There are several options offered for maximum customization like: velocity (for the animation particles), interval between each slide or label display on/off.Another nice feature is the ability to mention the animation type for each slide as a class name which allows us to use multiple animation types inside one slideshow

Wirify is a bookmarklet that lets you turn any web page into a wireframe in one click. It’s lightweight and works in many modern browsers.
Uses jQuery to calculate the dimension of the elements in the page and displays them “wirified”.

The plugin will get your list, wrap it into a container div, generate as many lists as the number of columns you require and evenly split the list items into the different list elements. If the list items are not enough to evenly fill in all the columns, the plugin will hide the columns in excess (this might happen only if you’re ordering your list items vertically as per default).

Easy Accordion plugin will get your definition lists (DTs) and generate a nice and smooth horizontal accordion. You can then decide to make it a timed slideshow or leave it still.
Easy Accordion Plugin keeps the HTML to the minimum, is SEO friendly and fully accessible, uses the CSS rotation to rotate the slide titles (no need for images here!), works in all the major browsers, allows for autoplay, it’s opensource and fully customizable and, what count most, it’s free!

Let’s pretend that this is a broken link. Can you imagine that when your users click this link, instead of them being redirected to a 404 error on your site, a friendly modal message pops up on your current page saying that it’s not available?. In that same message box you can then give them a sense of direction so that they’re not lost – you could ask them to click on a contact link to report the link’s broken, offer an alternative mirror, recommend they do a site search for the file or just say that you’re experiencing hosting issues and the file will be back up soon. The choice is completely up to you. The benefit of Catch404 is that you can offer your users a better experience when errors are encountered on your site.
